Method and User Equipment for Receiving Downlink Signals

1. A method for receiving, by a user equipment (UE), downlink signals in a wireless communication system, the method comprising: receiving, by the UE, configuration information of an inactive DRX, wherein the configuration information includes information about an inactive DRX cycle; monitoring, by the UE, a first physical downlink control channel (PDCCH) for receiving a paging message using a paging discontinuous reception (DRX) with a paging DRX cycle; based on the paging message being received and based on the paging message including an indication that there is downlink data for the UE: transitioning, by the UE, from the paging DRX with the paging DRX cycle to the inactive DRX with the inactive DRX cycle; and monitoring, by the UE, a second PDCCH for receiving the downlink data using the inactive DRX, wherein, based on the paging message including information about another inactive DRX cycle, the inactive DRX uses the another inactive DRX cycle included in the paging message instead of the inactive DRX cycle included in the configuration information.

2. The method according to claim 1 , wherein the UE is in a radio resource control (RRC) INACTIVE state.

3. The method according to claim 1 , wherein the UE transitions from the inactive DRX to the paging DRX based on receiving the downlink data.

4. The method according to claim 1 , wherein the UE transitions from the inactive DRX to the paging DRX based on transmitting an acknowledgement in response to reception of the downlink data.

5. The method according to claim 1 , wherein the UE transitions from the inactive DRX to the paging DRX based on the UE not receiving any PDCCH associated with the downlink data for a specific time duration.

6. The method according to claim 1 , wherein the UE transitions from the inactive DRX to the paging DRX based on receiving an indication that the UE enters the paging DRX.

7. The method according to claim 1 , wherein the paging message contains information regarding an identity of the UE, and wherein the UE monitors the PDCCH with the identity of the UE.

8. The method according to claim 1 , wherein the UE monitors the PDCCH in an on-duration of the inactive DRX.

9. A user equipment (UE) configured to receive downlink signals in a wireless communication system, the UE comprising: a radio frequency (RF) unit; at least one processor; and at least one computer memory operably connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising: receiving, by the UE, configuration information of an inactive DRX, wherein the configuration information includes information about an inactive DRX cycle; monitoring a first physical downlink control channel (PDCCH) for receiving a paging message using a paging discontinuous reception (DRX) with a paging DRX cycle; transitioning from the paging DRX with the paging DRX cycle to the inactive DRX with the inactive DRX cycle based on the paging message being received and based on the paging message including an indication that there is downlink data for the UE; and monitoring a second PDCCH for receiving the downlink data using the inactive DRX, wherein, based on the paging message including information about another inactive DRX cycle, the inactive DRX uses the another inactive DRX cycle included in the paging message instead of the inactive DRX cycle included in the configuration information.

10. The UE according to claim 9 , wherein the UE is in in radio resource control (RRC) INACTIVE state.

11. The UE according to claim 9 , wherein the operations further comprise: transitioning from the inactive DRX to the paging DRX based on receiving the downlink data.

12. The UE according to claim 9 , wherein the operations further comprise: transitioning from the inactive DRX to the paging DRX based on transmitting an acknowledgement in response to reception of the downlink data.

13. The UE according to claim 9 , wherein the operations further comprise: transitioning from the inactive DRX to the paging DRX based on not receiving any PDCCH associated with the downlink data for a specific time duration.

14. The UE according to claim 9 , wherein the operations further comprise: transitioning from the inactive DRX to the paging DRX based on receiving an indication that the UE enters the paging DRX.

15. The UE according to claim 9 , wherein the paging message contains information regarding an identity of the UE, and wherein the operations further comprise monitoring the PDCCH with the identity of the UE.

16. The UE according to claim 9 , wherein the operations further comprise monitoring the PDCCH in an on-duration of the inactive DRX.
